Before Winter Hits, Do This to Your Aquarium (Or Pay for It the First Cold Night)

🔗 Save $1,400 A Year with My Complete Aquarium-Saving Methods I teach: https://isamuyoshida.com Winter doesn't kill fish slowly — it kills them in a single night, the first hard cold snap your tank isn't ready for, when a heater fails or the power goes out and the water falls. And it's never the cold itself; it's the sudden swing. In this video, a koi keeper from the snow country of Niigata shows you exactly what to do now, in the warm, to carry your fish safely through winter — where to stand the tank, how to feed and change water as it cools, how to beat cold-season ich, how to insulate, why to run two heaters instead of one, and the power-outage failsafe that saves the whole tank on the worst night of all. Cheap, old-way, and done before you need it.
